Package: src:gimp-help
Version: 2.10.34-2
Severity: serious

Dear maintainer:

During a rebuild of all packages in unstable, your package failed to build:

--------------------------------------------------------------------------------
[...]
 debian/rules clean
dh clean --with gnome --no-parallel
   dh_auto_clean -O--no-parallel
   dh_autoreconf_clean -O--no-parallel
   dh_gnome_clean -O--no-parallel
   dh_clean -O--no-parallel
 debian/rules binary
dh binary --with gnome --no-parallel
   dh_update_autotools_config -O--no-parallel
   debian/rules override_dh_autoreconf
make[1]: Entering directory '/<<PKGBUILDDIR>>'
NOCONFIGURE=1 dh_autoreconf ./autogen.sh
Looking for latest automake version ... 
  You must have automake 1.10 or newer installed to compile gimp-help.
  Download the appropriate package for your distribution,
  or get the source tarball at ftp://ftp.gnu.org/pub/gnu/automake/

Please install/upgrade the missing tools and call me again.

dh_autoreconf: error: ./autogen.sh returned exit code 1
make[1]: *** [debian/rules:10: override_dh_autoreconf] Error 25
make[1]: Leaving directory '/<<PKGBUILDDIR>>'
make: *** [debian/rules:4: binary] Error 2
dpkg-buildpackage: error: debian/rules binary subprocess returned exit status 2
--------------------------------------------------------------------------------

The above is just how the build ends and not necessarily the most relevant part.
If required, the full build log is available here:

https://people.debian.org/~sanvila/build-logs/202502/

About the archive rebuild: The build was made on virtual machines from AWS,
using sbuild and a reduced chroot with only build-essential packages.

If you could not reproduce the bug please contact me privately, as I
am willing to provide ssh access to a virtual machine where the bug is
fully reproducible.

If this is really a bug in one of the build-depends, please use
reassign and add an affects on src:gimp-help, so that this is still
visible in the BTS web page for this package.

Thanks.
